Fortunately, out of the many, many, many people I’ve had over to my island, I’ve only ever had one negative experience.
I have a swap shop by my airport with a few items in. Not many, 4 furniture, 2 clothes and 2 wallpaper / flooring. It’s not expensive or rare stuff. Just a little something that people can use if they like.
I had my gates open the other day cause Celeste and Leif were over. I fenced off my town hall and path there and set up a queue on the turnip exchange. I left my switch idle whilst I watched some tv and basically trusted people to visit and sort themselves out. I didn’t charge an entry fee because I was just trying to help people out and having my switch in idle whilst I watched TV didn’t really effect me at all.
I’m really happy to say that 99% of the people that visited that night were extremely polite, respectful and kind! This experience has in no way clouded my opinion of online play because the vast majority of people are lovely!
But I did have one person steal all of the items from the swap shop. I’m not sure who it was, as like I said I wasn’t watching my switch at the time so didn’t realise until everybody had already been and gone.
The thing that irritates me more is the spite of it. The items weren’t expensive or rare. I doubt they would have gotten even 10k from selling them all. They not only took advantage of the kindness of allowing someone to visit their island for free. But they also took away the opportunity for anybody else to use the swap shop that night.
This experience won’t stop me from having people over or even having people over when I’m not watching the switch. But unfortunately now, if I’m not watching the switch, the Swap Shop and free fruit stand will be shut to be sure people don’t take advantage of it.
